When it comes to Linux server security, ClamAV and cPFence offer different solutions to the same problem: protecting your server from malicious attacks. In this post, we’ll dive into how ClamAV performs, why we incorporate it into cPFence, and why cPFence goes beyond what ClamAV alone can offer.
1. ClamAV: A Great Product with Powerful Scanning
ClamAV has earned its place as a respected antivirus solution, widely used in the industry for its robust scanning capabilities. Many security products, including cPFence and others like cPGuard and ConfigServer eXploit Scanner (cxs), leverage ClamAV as part of their scanning systems. However, ClamAV alone may not provide the comprehensive security that Linux hosting servers require, especially for PHP-based infections, which are particularly common in shared hosting environments.
2. ClamAV’s Limitations with PHP Malware Detection
While ClamAV is powerful, its virus detection rate is less effective for PHP malware, which is particularly common in shared hosting environments. Most malicious attacks on Linux hosting servers target vulnerabilities in PHP applications, which are central to many websites.
3. ClamAV Detection Rate: Reported vs. Real-Life Scenarios
Officially, some sources place ClamAV’s detection rate at around 60% for general malware (e.g., Splunk’s report on ClamAV’s detection of commodity malware). However, our tests reveal that ClamAV’s effectiveness drops significantly when faced with real-life, fresh PHP malware, with detection rates between 20% to 35% at best. This gap highlights why relying solely on ClamAV can leave your server exposed.
4. Independent Tests Show Similar Findings
In fact, other independent testers report similar detection limitations for ClamAV in real-world scenarios. A recent test by the Anti-Malware Alliance (October 2024) underscores these findings, especially for PHP-based threats.
5. PHP Malware: The Most Common Threat in Shared Hosting
In shared hosting environments, malware infections are overwhelmingly PHP-based, making up over 90% of infections. This statistic highlights the importance of an antivirus solution specifically optimized for PHP malware. Without strong PHP detection, server protection remains incomplete, exposing your business and users to significant risk.
6. cPFence’s Malware Database: An Industry Leader
cPFence stands out with an extensive malware database that offers the most comprehensive protection for Linux servers. Not only is it affordable, but cPFence is also the most advanced antivirus option in the industry for Linux hosting environments. Our database includes over 14 million virus signatures, covering a wide array of threats.
7. Real Malware, Real Protection: cPFence’s Signature Database
cPFence signatures are derived from real-world malware samples, especially those found on busy hosting servers with PHP and WordPress sites. Our smart, generic signatures enable the detection of zero-day threats, while hourly database updates ensure your server is always protected.
8. Proven Detection Rate of 95%+
Based on our extensive testing, cPFence consistently achieves a detection rate of over 95%, offering significantly stronger protection than ClamAV for Linux hosting servers. We invite you to test our product yourself: download PHP malware samples, scan them with ClamAV, then scan again with our free trial of cPFence. You’ll see first-hand how cPFence excels in detecting threats that ClamAV misses.
9. Test cPFence Risk-Free
Testing is easy and affordable. Set up a cloud VPS with Hetzner (billed hourly for minimal cost), download some PHP malware samples, and scan with both ClamAV and cPFence. With cPFence, you’ll likely see over a 95% detection rate. If there’s any malware we miss, we encourage users to report it through our submission portal; updates are made in just 60 minutes.
10. Lightweight and Resource-Efficient
ClamAV is known for its high resource usage, demanding substantial CPU and memory. By contrast, cPFence is designed to be lightweight and efficient, making it ideal even for smaller servers. With cPFence, only modified or newly added files are scanned using our extensive malware signatures, which keeps resource use to a minimum. If malware is detected, it’s immediately quarantined, and the admin is notified.
11. cPFence: More Than Just Antivirus
cPFence goes far beyond standard antivirus, offering a full range of security modules to protect your server on multiple fronts:
- DDoS Protection: Safeguard your server from disruptive DDoS attacks, ensuring uptime and stability.
- Email Server Malware and Spam Protection: Keep your email servers secure and free from malware and spam, protecting your communication channels and user inboxes.
- cPFence Owl™ Module: Our intelligent threat-detection module monitors, analyzes, and blocks threats in real-time, ensuring a proactive defense.
- Smart 24/7 Process Monitoring with Automated Actions & Instant Malware Blocking: Constantly monitors processes to detect abnormal activity, with automated actions to halt threats instantly.
- MySQL Resource Management: Limit abusive, long MySQL queries to prevent database overuse and ensure smooth performance.
- Rootkit Scanner: Detects and removes hidden rootkits, securing your server from advanced, stealthy threats.
- Bot Protection: Blocks over 800 known malicious bots, keeping harmful automated traffic away from your applications.
- Hourly Updated IP Database: Prevents malicious IP addresses from reaching your server, ensuring only legitimate traffic gets through.
